Translation guide
A risk factor is something that increases the chance of a negative outcome, such as disease, accident, or failure. In Japanese, the most direct equivalent is 危険因子, but depending on context, other terms like リスク要因 or リスクファクター are used. This guide covers how to express the concept naturally in medical, business, and everyday situations.
A factor that increases the likelihood of developing a disease or health condition.
Standard medical term for risk factor. Used in clinical and public health contexts.
Smoking is a risk factor for lung cancer.
Also common in medical literature, slightly more modern or research-oriented.
High blood pressure is one of the risk factors for stroke.
Any element that increases risk in non-medical contexts, such as business, safety, or personal decisions.
危険因子 is primarily medical, while リスク要因 is used in business, finance, and general risk analysis. Using 危険因子 outside of health contexts may sound overly dramatic or clinical.
Directly translating 'risk factor' as 危険要因 is not standard and may confuse listeners. Stick to the established terms above.
Loanword from English, used in business and technical contexts. Sounds slightly more casual or jargon-like.
